Applying Detergent with the
Adjustable Nozzle
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could damage
the pump.
IMPORTANT:You must attach all hoses before you
start the engine. Starting the engine without all the hoses
connected and without the water turned ON will damage
the pump.
To apply detergent, follow these steps:
• Review the use of adjustable nozzles.
• Prepare the detergent solution as required by the job.
• Hang the detergent solution on the hook of the
wireform attached to the handle, as shown in Figure 14.
• Place the filter end of the detergent siphoning tube into
the detergent container.
CAUTION! Keep the detergent siphoning tube from
coming in contact with the hot muffler.This will damage the
plastic tube.When inserting the filter into a cleaning
solution bottle, route the tube so as to keep it from
inadvertently contacting the hot muffler.
• Slide the adjustable nozzle forward to low pressure
mode. Detergent cannot be applied with the nozzle in
high pressure position.
• Make sure the garden hose is connected to the pumps
water inlet. Check that the high pressure hose is
connected to the spray gun and the pump (see “Connect
Hose and Water Supply to Pump”, page 7). Start the
engine.
• Apply detergent to a dry surface, starting from the
bottom and working up.
• Allow the detergent to “soak in” for 3-5 minutes before
washing and rinsing. Reapply as needed to prevent
surface from drying.
• For washing, start at lower portion of area to be washed
and work upward, using long, even, overlapping strokes.
Pressure Washer Rinsing
WARNING! Be extremely careful if you must use
the pressure washer from a ladder, scaffolding or any
other relatively unstable location.Pressure in a
running washer builds as you climb.When you press
the trigger, the recoil from the initial spray could
cause you to fall.The high pressure spray could also
cause you to fall if you are too close to the cleaning
surface.
For Rinsing:
• Slide the nozzle backward to high pressure, press the
trigger and wait for the detergent to clear.
NOTE:You can also stop detergent from flowing by simply
removing detergent siphoning tube from bottle.
• Keep the spray gun a safe distance from the area you
plan to spray.
• Apply a high pressure spray to a small area, then check
the surface for damage. If no damage is found, it is okay
to continue cleaning.
• Start at the top of the area to be rinsed, working down
with same overlapping strokes as you used for washing
and applying detergent.
Automatic Cool Down System
(Thermal Relief)
If you run the engine on your pressure washer for
3-5 minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach a temperature
between 140–145°F.When the water reaches this
temperature, the automatic cool down system engages and
cools the pump by discharging the warm water onto
the ground. This system prevents internal damage to the
pump.

PRESSURE WASHER
MAINTENANCE
Check and Clean Inlet Screen
Examine the screen on the water inlet. Clean it if the
screen is clogged or replace it if screen is damaged.
Check High Pressure Hose
The high pressure hose can develop leaks from wear,
kinking, or abuse. Inspect the hose each time before using
it. Check for cuts, leaks, abrasions or bulging of cover,
damage or movement of couplings. If any of these
conditions exist, replace the hose immediately.
WARNING!Water spraying from a leak is capable
of injecting material into skin. Inspect hose each time
before using it. Never repair a high pressure hose.
Replace it with another hose that exceeds the
maximum pressure rating of your pressure washer.
Check Detergent Siphoning Tube
Examine the filter on the detergent tube and clean if
clogged.The tube should fit tightly on the barbed fitting.

time. Sediments or minerals can deposit on pump parts and
“freeze” pump action. If you do not plan to use the pressure
washer for more than 30 days, follow this procedure:
1. Flush detergent siphoning tube by placing the filter into
a pail of clean water while running pressure washer in
low pressure mode (adjustable nozzle in the forward
position). Flush for one to two minutes.
2. Shut off the engine and let it cool, then remove high
pressure and garden hoses.Disconnect spark plug wire
from spark plug.
3. Empty the pump of all pumped liquids by pulling the
recoil handle about 6 times.This should remove most
of the liquid in the pump.
4. Use Generac brand PumpSaver to prevent corrosion
build up and freezing of pump.
5. Store unit in a clean, dry area.

Protecting the Pump
To protect the pump from damage caused by mineral
deposits or freezing, use the Generac PumpSaver to treat
pump.This prevents freeze damage and lubricates pistons
and seals.
NOTE: Generac PumpSaver, model number 01559, is
available as an optional accessory. It is not included with the
pressure washer.
CAUTION!You must protect your unit from freezing
temperatures. Failure to do so will permanently damage
your pump and render your unit inoperable. Freeze damage
is not covered under warranty.
CAUTION! Read and follow all cautions and
warnings on the PumpSaver can label.Always wear
eye protection when using PumpSaver.
To use PumpSaver, make sure the pressure washer is
turned off and disconnected from supply water. Read and
follow all instructions and warnings given on the
PumpSaver container.
NOTE:PumpSaver will drip from pump after treatment
and will stain wood and concrete.
NOTE: If PumpSaver is not available, draw RV antifreeze
(non-alcohol) into the pump by pouring the solution into a
3-foot section of garden hose connected to inlet adapter
and pulling recoil handle twice.
